Oracle Exadata X82 Datasheet !full!
The Oracle Exadata X8-2 Database Machine is an engineered system designed to optimize performance, scalability, and availability for Oracle Database workloads. It features a scale-out architecture with database compute, intelligent storage, and high-speed InfiniBand networking. Compute Server Specifications
Performance Features
- Smart Scan: Pushes SQL predicate, column projection, and aggregation processing to storage servers to reduce CPU and I/O on database servers.
- Storage Indexes & Smart Flash Cache: Minimize physical I/O by tracking value ranges and caching hot data in flash, improving query response.
- Hybrid Columnar Compression: High compression ratios for analytic workloads to reduce storage footprint and I/O.
- RDMA-based I/O: Lowers CPU overhead and latency for large parallel query and OLTP workloads.
- Persistent Memory & NVMe: Offers very low-latency storage for redo and high-performance I/O paths.
Software Compatibility (What runs on X8-2?)
The hardware is useless without the correct software stack. According to the X8-2 certification datasheet: oracle exadata x82 datasheet
Each X8-2 database server is a 1U rack-mount system optimized for compute density. Specification Processors 2x 24-core Intel® Xeon® Platinum 8260 (2.4 GHz) Memory 384 GB standard, expandable to 768 GB or 1.5 TB Storage 4x 1.2 TB hot-swappable hard disks (expandable to 8) Networking The Oracle Exadata X8-2 Database Machine is an
- Hybrid Columnar Compression (HCC): The X8-2 continues to leverage HCC, offering compression ratios typically ranging from 10x to 15x.
- I/O Capacity: A single X8-2 Storage Cell contains 12 high-capacity 14TB HDDs, providing 168TB of raw disk capacity per cell.
- Intelligent Flash: The critical innovation lies in the flash layer. The X8-2 utilizes NVMe (Non-Volatile Memory Express) SSDs. Each cell contains four 6.4TB NVMe flash drives, delivering 25.6TB of flash capacity per cell. NVMe bypasses the traditional SATA/SAS bottlenecks, connecting directly to the PCIe bus, offering significantly lower latency and higher IOPS.
